WILLIAM W. GUEST, OF ALAMEDA, CALIFORNIA.

AMALGAMATOR.

Specification of Letters Patent.

Patented July 8, 191 3.

Application filed October 21, 1912. Serial No. 726,984.

To all whom it may concern Be it known that I, IVILLIAM 7. Guest, acitizen of the United States, residing at Alameda, in the county ofAlameda and State of California, have invented new and usefulImprovements in Amalgamators, of which the following is a specification.

My invention relates to an apparatus for amalgamation of precious andvaluable metals; in means for separating the material to be acted on,and means for providing ttreely turnable bearings and tight joints forthe passing material.

It comprises details of construction which will be more fully explainedby reference to the accompanying drawings, in which- Figure 1 is avertical section through the amalgamator. Fig. 2 is a cross section online X-X of Fig. 1. Fig. 3 is an enlarged detail view.

My apparatus generally consists of a container 2, through which theliquid, slime, or material to be treated is circulated by means of acentrifugal pump 3, connected with the lower part of the container by apipe at through which the pump continually draws the material intoitself and into the pipe 5 through which the material is ejected andreturned to the container.

Across the top of the container is fixed a beam 6 which serves tosupport the devices hereafter described. Above this beam is supported asecond beam 7, by means of standards 8 resting upon the beam (3, and thewhole secured together by screw-bolts and nuts as at 9.

10 is a pipe which may be united to the ipe 5 by a coupling flange, asat 11. The ower end of this pipe is enlarged and has fitted upon it anut 12.

13 is a pipe having a head at the upper end, turnable within theenlargement of the pipe 10, and the upper end is surrounded by aflexible washer 1a which is upturned around the sides of the pipe, andthe horizontal portion is clamped between the nut 12 and the lower endof the pipe 10, thus forming a tight, but flexible joint. The pipe 13extends down to near the bottom of the receiver 2, and has radiallydisposed arms 15 connected to its lower end and revolving in ahorizontal plane in the bottom of the container. These arms are providedwith inclined discharge pipes 16, the lower ends of which dip into abody of mercury,

as indicated at 17, so that material carried to the pipes will bedelivered into intimate contact with the mercury. The body of mercuryalso acts to cause this portion of the apparatus to continually revolvein a reactionary manner. The material after passing through the mercuryrises to the level of the pipe 4, and is again withdrawn by the pump 3,and again circulated thrm'lgh the apparatus. in order to guide andsteady this revolving tube 13 and its appendages as shown surroundingit, I have provided a tube 18, having a. l'lange adapted to rest on thebeam (5, and the upper surface of the flange having grooves "forball-bearings, as shown at it). The other member 20 of the ball-bearingis secured to the pipe 13, and has ball-bearing grooves in its lowerface corresponding with those in the part 18. The lower end of the tube18 is beveled to form bearings for balls, as at 21.

Fixed to the pipe 1 3 is a tubular structure J2, the upper portion ofwhich surrounds the pipe 18 with an annular space between, and the lowerend is drawn in and keyed or otherwise secured to the lower end of thepipe 13, and revoluble with it. The inwardly curved lower portion ofthis part 22 forms the complementary bearing for the balls 21.. Thus thetube 13 with its radiating arms 15 is supported between the balls 18)and the balls 21, which are at such a distance apart as to form asulliciently rigid guide For the revoluble tube and its attachments, andit is thus not necessary to nrovidc any step at the bottom of the pan orcontainer, which is thus leitt perfectly clear of all obstructions.

In order to provide for any possible leakage which may take placethrough the joint shown at 1 1, I have shown a drip plate. 23 which isin the form of an inverted pan, inclosing a bearing plate :20 and theupper end of the tube 18, and any drip or leakage which may occurthrough the joint at 1st will be guided outwardly and fall into thereceiver 2.

An electrical circuit is maintained through the apparatus, consisting ofpositive electrodes connecting with the interior of the pan, as at 2i,and the negative electrodes leading outwardly from the body 01 mercurywithin the pan, as at 525; the circuit being maintained by any directcurrent geuer" ator, not shown.

Having thus described my invention, what I claim and desire to secure byLetters Pattent, is- I 1. In an apparatus of the character described, avertical pipe through which the slime is brought to the apparatus, avertical pipe in line therewith, a receiver into the bottom of whichsaid pipe extends with radial arms and tangential discharges, a flangedtube supporting and surrounding the said pipe, and having ball bearingsupports at its upper and lower end, and cooperating bearing membersfixed with relation to the upper and lower end, the lower member beingconnected with the revoluble pipe.

2. In an apparatus of the character described including a container, abeam fixed across the top thereof, a tube having a ball bearing flangeat the top, said flange resting upon the beam, and said tube having aball bearing formed at the lower end thereof, a vertical pipe extendingthrough said tube and having radial arms and discharge nozzles adaptedto convey material into the pan, a sleeve having its lower end fixed tosaid tube, said sleeve being enlarged to inclose the lower end of theball bearing tube and having a ball bearing support formed to cooperatewith that of the lower end of the tube.

In testimony whereof I have hereunto set my hand in the presence of twosubscribing witnesses.

WILLIAM W. GUEST.
